The wood weaving machine herein set forth embodying the principles of myinvention comprises a means for feeding the warp formed of ribbons ofwood and located at what is hereinafter termed a head end of the deviceand as indicated by arrow G, see Fig. 2, a tension and guide means forcontrolling the feed of the warp positioned immediately following thefeed means and indicated by an arrow H, a healding means for alternatelycrossing alternate strips of warp following the guide means locatedabout the center of the device, a, gluing means operating on the 'warpand a shuttle for carrying the weft operating in the device immediatelyfollowing the healding means and clamping means for properly holding andpulling the wooden fabric, being positioned in what is hereinaftertermed a tail end of the device.

More specifically a frame for supporting the various functioning partsof the device comprises base members 1, 1, and having a superstructureformed of the members 2, 28, 3-4:, 4e-5,"56, 6-7, 78, 8- and 9 9.

At the head end of the device is mounted a gang of reels 10 carryingwood ribbons 11 forming half of the warp. Below the reels 10 andstaggered relative to their vertical position is a second gang of reels12 carrying wood ribbons 13 forming the other half of the warp. The twogangs of reels are supported from cross bars 14L which are formedintegral with the uprights 2, 2 of the frame.

With reference to Fig. 17, the reels are formed of two disks 15 spacedby a hub 16 which carries a central bore 17. The reels are supported bythe arms 18 extending downwardly from the cross bars 1 1. A. bearing isformed at the lower end of each arm having an opening 19 in the topside, the bearings in the arms being adapted to slidably carry stubshafts 20. The stub shafts 20 are of such length as to extend beyond theface of the arms 18 and are adapted to the bore 17 of the reel hubsforming a bearing upon which the reels rotate.

A groove 21 is cut at the center of each shaft. A finger 22 ispositioned with a lower end fitted to the groove 20 of each shaftthrough the opening 19, the fingers being pivotally mounted verticallyabove each bearing by a cap screw23 to the cross bar 14. Below thebearing on each of the arms 18 is a spring pocket 24E carrying a coilspring 25 which bears at its top end against a ball 26, the lower end ofthe spring being carried by an adjusting screw 27, the balls 26 beingadapted to partially enter the grooves 21 of the stub shafts to keep theshafts from drifting.

The warp running from the reels 10 passes through the outer ends oftension springs 28, under a roller 29, through guides 30 and under aroller 31. The warp running from the reels. 12 passes through tensionsprings 32 over a roller 33 through guides 34 and over a roller 35.

There is a tension spring for each strip of the warp they being formedof an inner blade 36 and an outer blade 87. The inner blade 36 extendsbeyond the outer end of the outer blade, the extension being bentupwardly so that it is on the same plane with the outer blade. The innerblade is also formed with ears 38 at its outer end adapted to be bent upover the end of the outer blade so-that the outer blade is slidablycarried by the inner blade. The outer blade is notched as shown in Fig.10 forming a central extending tongue 39. The in ner blade has a slot i0adjacent to its outer end and from the inner edge of the slot 40 theblade is bent upwardly the thickness of the blade and outwardly so thatwhen the outer blade is slipped under the ears 38 of the inner blade thetongue 39 will partially close the slot 10.

Between the members 5, 5 of the frame is positioned a cross bar ll forcarrying the upper set of tension springs 28 adapted to operate upon thewarp strips 11 and between the members a, 1 of the frame is fixed asecond cross bar 42 carrying the lower set of tension springs adapted tooperate upon the warp strips 13. The cross bars 4L1 and 42 are formed ofa base member having two outwardly extending members 13 and 4st. Themember 43 carries a rectangular slot for each tension spring throughwhich the spring is passed, the inner blade 36 being screwed to thecross bar by a screw 45 while the outer blade remains slidably mountedin the member 43. Through the extension is is screwed an adjusting screw46 having set nut 47 the inner end of which bears against the end of theouter blade of the tension spring.

The roll 29 is rotatably mounted transversely of the warp strips 11 in avertical member 49 extending upwardly from the member 3 of the frame 1.The roll is rotatably mounted transversely of the warp strips 13 in thevertical member 49, the rolls 29'and 33 being positioned to bear evenlyupon all the warp in the upper and lower sets respectively. I

The guides 30 and 3a are rectangular in form and have belled ends asshown to prevent the warp from cutting on the edges of the openings, theinner measurement of each guide opening being slightly greater than thewidth and thickness of the warp strips. These guides are too wide to beset side by side on the same level and so are set on two levelsstaggered as shown in Fig. 11, the inside edge of one guide slightlyoverlapping the inside edge of the next so that the warp strips arebrought closely together. The two sets of guides are carried by a crossbar 48 mounted between the members 5 of the frame. 8

The rolls 81 and 35 are rotatably mounted in a vertical member 50 fixedto the member 3 of the frame, they being positioned to bear properlyupon the upper and lower sets of the warp strips respectively.

The uprights 6, 6 extending vertically from the base 1 of the frame havechannels in their inside faces adapted to form guides for two healdframes 51 and 52. The frame 51 is composed of the side members 58, a topbar 5 1 and a bottom bar 55, the second frame being like the firstcomprising the side members 56, 56 and a top bar 57 and a bottom bar 58.The frame 51 carries, extending downwardly from the top bar 5-1, arms 59which reach nearly to a central line between the top and bottom barsthere being an arm positioned to each alternate strip of the warp, andextending upwardly from the bottom bar are like arms 60 having a lengthextending them nearly to the end of the arms 59, there being a spacebetween the ends of the two arms for carrying a strip of the warp, eachset of arms in the frame registering on vertical lines.

Extending downwardly from the top bar 57 of the frame 52 are other arms61 like those of the frame 51 positioned between the arms of the frame51 and reaching nearly to a central line between the top and bottombars, and from the bottom bar 58 are other like arms 62 extendingupwardly and reaching nearly to the end of the downwardly ex tendingarms 61 and registering therewith on vertical lines so that the arms 61and 62 will carry alternate strips of the warp.

The arms 59 and 60 of the frame 51 are formed at their inner ends with arounded port-ion 68, 63 extending toward the head end of the device andthe arms 61 and 62 of the frame 52 are formed at their inner ends with arounded portion 64, 64: extending toward the tail end of the device. Thearms are slightly narrower than the strips of the warp and the framesare adapted to pass .each other with the round-ed portions 63 and 61passing in a vertical line. The inner ends of the arms are otherwise soformed that the strips of warp will always be bent over a properlyrounded surface.

The frames are operated vertically by a rock arm 65 fixed to a rockshaft 66 being connected with the frame 51 by a link 67. The rock shaft66 is operated by a shaft 68 rotatably mounted transversely of the,frame and carrying a cam plate 69 having a forked cam groove 70. A yoke71 is mounted astride the shaft 68 having a pin and roller 72 forengaging the groove of the cam. A downwardly extending portion 73 of theyoke 71 carries a rack which engages a gear 74 on the rock shaft 66. Therack 73 is kept in mesh with the gear 74 by a roller guide 75 on theback side of the rack, the rock shaft 66 and roller 7 5 being mounted ina standard 76. The rock arm 65 is connected to the frame 51 by a link 67and to the frame 52 by a link 67 Facing the device at the head endthereof, one side shall be hereinafter designated as a right hand sideand the other side as a left hand side.

A driving shaft 78 for the device is mounted in a bearing 79, 80, 81, onthe right hand side. The driving shaft carries a pinion 82 which mesheswith the gear wheel 88 fixed upon the transverse shaft 68. Toward therear end of the device on the shaft 78 is fixed a cam 81, a cam 85, acam 86, a cam 87 and a cam 88. On the left hand side of the device fromthe driving shaft is mounted upon the transverse shaft 68 a bevel gear89.

A longitudinal shaft 90 is mounted in bearings 91 and 92 and carries apinion gear 93 meshing with the gear wheel 89. The shaft 90 carriesa-cam 9 1, a cam 95 and a cam 96 and a cam 97.

The drive shaft 78 runs clockwi e, the transverse shaft 68 runscontra-clockwise and the shaft 90 runs contra-clockwise.

The cams 84, 85, 87 and 88 respectively, on the shaft 78 are identicalin form and throw to the cams 91, 95, 96 and 97 respectively, on theshaft 90 except that the two shafts are turning in opposite directionsand the cams are adapted to work together in pairs on the oppositelyturning shafts.

Carried upwardly from the base are two vertical members 98, 98, at thetop of which and transversely of the device is fixed a beam 99 forming atop stationary member of a weft clamp 100 and a second beam 101 besidethe beam 99, and spaced properly therefrom, forming a top stationarymember of a holding clamp 1052. Below the stationary beam 99 ispositioned a beam 103 having its ends extending through guides 1041 inthe vertical members 98, 98 being mounted in the guides to movevertically. Links 105, 105 are pivotally connected to each-end of thebeam 103 and extend downwardly and are pivotally connected to horizontalrock arms 106, 106, the inner ends of which are pivotally connected tothe upright members 98, 98. The arms 106, 106 extend outwardly over thecam 8st on the right hand side and the cam 94 on the left hand side andeach carries a wheel 107, 107 adapted to bear upon each of the cams sothat the beam 108 will be raised evenly by the operation of the two camsand bear with pressure against the stationary beam 99. Below thestationary beam 1.01 is a vertically movable beam 108 having its endsslidably mounted in slots 109, 109 in the vertical members 98, 98 andadapt ed to form a clamping means with the stationary member 101. Links110, 110 are pivotally connected to the outer ends of beam 108, thelower ends of the links being pivotally connected to horizontal rockarms 111, 111, the inner ends of the rock arms being pivotally connectedto the vertical members 98, 98, their outer ends extending out over thecam 85 on the right hand side and the cam 95 on the left hand side andcarries rollers 112, 112, which bear upon the cams so that by a rotationthereof the beam 108 will be raised evenly and bear against thestationary beam 101. v

A pair of vertically disposed arms 113, 113 are pivotally connected withthe base 1 by a transverse shaft 114. Across the top of the arms isfixed a beam 115 which forms an upper stationary member of a clamp 116forming a part of a discharge mechanism for the device. Below the beam115 is positioned a parallel beam 117 mounted to move vertically in slot118, 118 in the arms 113, 113. Links 119, 119 are pivotally connected tothe outer ends of the beam 117 and extend downwardly, being pivotallyconnected at their lower end to horizontally disposed rock arms 120,120, the rock arms being pivotally connected to the vertical arms 114,114 and. extending outwardly over the cam 88 on the right hand side and97 on the left hand side and carrying the rollers 121, 121 for engagingthe cams so that by their operations the beam 117 will be raised evenlyso as to bear with pressure against the stationary beam 116.

The pivotally mounted arms 113, 113 also carry rollers 122, 122positioned to engage the face of the cam 87 on the right hand side and96 on the left hand side of the device so that by the operation of thecams the arms will be carried backwardly in unison thus carrying thefeeder clamp 11G backwardly. Retractile springs 123, 123 are connectedat one end with the frame of the device forwardly of and at the otherend with the arms 113, 113 whereby the arms may be pulled forwardkeeping the rollers 122, 122 in contact with the faces of the cams 87and 96.

The strips of warp passing from the reels 10 and 11 at the head end ofthe device through the tension springs 28 and 32, under and over therollers 29 and 33 through the guides 30 and 34, under and over therollers 31 and 35 is passed through between the ends of the arms 59 and60 of the heald frame 51 and 61 and 62 of the heald frame 52 thencethrough between the weft clamp 100, the holding clamp 102 and thedischarge clamp 116, the weft being woven in with the warp prior to itsentrance into the weft clamp.

The weft clamp, the holdin clamp and the discharge clamp are notched asshown in Fig. 18, forming teeth in each member of each clamp, whichregister with each other, whereby, with a proper setting of the clamps,the teeth clamp always in the centers of the warp, on one side, and theweft upon the other side of the fabric. Such a construc tion is used sothat the glue which might be pressed out from between the joints of warpand weft will not wet and gum up the clamps.

A shuttle carriage 125 is positioned at the right hand side of thedevice extending outwardly therefrom and backwardly of the heald frames.The carriage comprises a back plate 126 having a plurality of groovedtop rollers 128, 128 and grooved bottom rollers 129, 129. Extendingoutwardly and downwardly from the plate 126 is an arm 130 at the outerend of which is rotatably mounted a weft reel 131 from which the weft132 may be fed into the fabric to be produced by the device.

The weft passing from the reel 131 passes through a tension spring 133over a roller 134 and through a guide 135, the guide and roller beingfixed to the back plate 125 by means of a bracket 136 which is formedintegral therewith and the spring 133 is carried by an arm 137 which isalso carried by the bracket 136. The tension spring 133 is of the samedesign and operates in the same manner as the tension springs 28 and 32through which the warp is fed.

The carriage 125 is mounted to swing longitudinally of the device beingcarried by three sets of rock arms 138, 139 and 140, they beingpivotally mounted at the base ends and pivotally connected to thecarriage 125.

The main shaft 7 8 carries a cam 141 having a cam groove 142 within itsface and an extending hub 143, the hub being mounted upon the shaft sothat it will rotate therewith but loosely fitted in longitudinal keyways so that it may slide longitudinally of the shaft. A stationary camplate 144 is fixed positively to the bearing 7 9 of the main shafthaving an irregular face formed to operate with aroller on the oppositeside from the groove 142 of the cam 141 whereby that cam will be movedtoward the rear end of the device along the shaft 78 by the rotation ofthe shaft. Bearing standards 145 and 146 extend outwardly from the plate126 and carry slidably a screw 147, the screw operating through athreaded bore of a gear wheel 148. At the lower end of the screw isfixed a yoke 149 which straddles the hub 143 of the cam.

Integral with the back plate 126 is an arm 149 extending outwardlytoward the top of the cam 141 on which is rotatably mounted a guidewheel 150 which bears against the face of the cam so that by a rotationof the cam with the shaft the cam is moved toward the tail end of thedevice and through the guide roller 150 the carriage 125 is also carriedin that same direction. A coil spring 151 fixed at one end to theshuttle carriage and at the other to a bracket 152 causes a returnmovement of the shuttle carriage and cam. The rock arms 138, 189 and arein pairs as shown in Fig. 4. When the roller in the face of the cam 141engages the sta tionary cam plate 144 the cam 141 slides to ward therear on the shaft 78 and through the roller pushes backwardly the plate126. he rocker arms 188, 139 and 140 being in parallel sets cause theplate 126 and the shuttle to maintain a level position, and the shaft147 is therefore maintained in vertical alinement with the threaded boreof the gear wheel 148 throughout the travel of about one-half inch. Therods 188, 189 and 140, being pivoted at the top and bottom, willtherefore not be snapped. The yoke 149 *arries a roller and pin 158which engages the cam groove 142 causing a vertical movement of thescrew 147 and a rotation of the gear wheel 148.

A shuttle comprising a T beam 154 is mounted with its cross member 155disposed between the upper rollers 128, 128 and the lower rollers 1.29,129 and its stem portion 156 pointing toward the tail end of the device.On the back of the shuttle is fixed a toothed rack 157 positioned tomesh with the gear wheel 148 whereby through the rotation of the gearwheel the shuttle is run back and forward transversely through betweenthe two sets of warp strips.

The outer end of the stem portion 156 is split forming a groove 158having a very thin retaining wall above and below. A cam shaft 159 ismounted upon the stem portion of the shuttle in bearings 160, 160 and161, 161. Flee Figs. 18. 14, 15 and 16. Spring blades 162, 162 are fixedto the cross member of the shuttle and pass outwardly beneath the camshaft. their outer ends bearing upon the upper retaining wall of thegroove 158. Cains 168 are formed on the shaft 159, there being oneadapted to engage each of the plates 162, 162.

The cam shaft 159 has a lever 164 fixed to its outer end which when thephuttle is moved outwardly engages an arm 165 which throws the arm 164downwardly causing the cams 168. 168 to pass under the center of theshaft pressing the plates 162 downwardly thereby pressing the top wallof the crevice downwardly and partially closing the crevice. On the endof the outer pivot of the rock arm 106 which carries a roller 107, onthe right hand side of the device, is fixed a stiff rod 167 positionedto engage the lever 164 of the cam shaft 1 9, when the shuttle passesinwardly, and throws it upwardly thereby releasing the plates 162, 162and widening the crevice 158.

(in the left hand side of the device is an outer shuttle bearing 169which carries a pocket having a retractile spring 170 and adapted toreceive the free end of the shuttle. The bearing is carried pivotally bya pair of rock arms 171 pivotally mounted in the base 1. A double actingcam 172 is fixed on the transverse shaft 68 and carries a groove 173adapted to engage a roller and pin 174 on one of the rock arms 171whereby the shuttle when entered into the bearing may be movedlongitudinally of the device in unison with the movement of the carriage125. I

On the right hand side of the device and mounted upon a standard. 98 isa shear for cutting off, at a proper time, the strips of weft carriedinto the loom by the shuttle, comprising blades 176, 176 pivoted withthe pin 177. The blades are carried between two cams 178, 178 havingarms 179, 179, the cams proper being formed on the inner ends of therotatably mounted shaft portions marked 178, 178, in Fig. 4. A link 181connects the two arms at their outer ends and a rod 182 connects thelower arm 179 with a horizontal rock arm 183 which is pivotally mountedupon the standard 98, its outer end reaching out over the cam 86 andhaving a roller 184 rotatably mounted on its outer end and engaging thecam. Retractile springs 185, 185 are fixed to the standard 98 at one endand fixed to the two blades of the shears at their outer ends causing areopening of the shears after a strip of weft has been cut by theoperation of the cams.

A gluing device 187 is mounted to operate upon the upper surface of theupper warp strips backwardly from the heald frames and adjacent to theweft clamp. lVith reference to Fig. 6; the gluing device comprises areceptacle 188 adapted to contain glue having a gridiron valve 189 inthe bottom which operated by the pair of arms 190 fixed to the rockshaft 191 having a hand lever 192 extending upwardly through the top ofthe vessel.

A roller 193 is rotatably mounted in bearings 194, 195 below the valve189 there being a funnel 196 disposed between the top of the roller andthe valve. A bevel gear 197 is fixed to the roller shaft. A second shaft198 mounted in a bearing 199, carries a second bevel gear 200 meshingwith the gear 197. The vessel carries two upper rollers 202, 202 and alower roller 203, the lowerroller being positively fixed to an extensionof the shaft 198.

The upper rollers 202 and the lower roller 203 are adapted to run on atrack 204 fixed horizontally across the vertical standards 6, 6. Thegluing device is operated transversely across the warp strips by a screw205 operating in a nut 206 which is fixed to the vessel. The roller 198has a slightly curved surface to register with the bend of the warp dueto the pressure of the roller thereon.

A second gluing device 207 is mounted to operate on the under surface ofthe lower set of warp strips. Thls under gluing means comprises a vessel208 adapted to contain glue and having a basin 209 fixed in the upperpart and an elevator 210 carried on a shaft 211 rotatably mounted inbearings 212, 212. The elevator carries on its periphery buckets 213adapted to elevate glue. The buckets have partitions dividing them intotwo compartments opening in opposite directions so that the glue will beraised with the elevator running in either direction. The buckets willdischarge the glue into the basin 209. The elevator also carries gearteeth upon a rim portion 2141.

In the upper part of the vessel is rotatably mounted in bearings 215 and216 a roller 217 positioned with its lower part into the basin 209.Projecting from the side of the roller is a circle of pins 218 whichengage the teeth on the rim 21 1 of the elevator. The roller shaft alsocarries a universal joint 219 connecting the roller shaft with a shaft220 at the outer end of which is a gear 221, the shaft being carried inbearing 222. The under gluing means is provided with two rollers 225 atthe top and a roller 226 at the bottom in the same arrangement as thetop gluing device 187, see Fig. 1.

The roller 225 is fixed to its shaft which rotates in bearing 227, andcarries a gear 229 which meshes with the gear 221.

The under gluing device 207 is adapted to be mounted upon a track 230fixed across the standards 6, 6 and is carried transversely of the warpstrips by a screw 231 operating in a nut 232 fixed to the vessel.

On the shaft 233 is a cam 237 having a groovedface. Astride the shaft 233 is a yoke 238 terminating at the top in aworm shaft 239 which extends upwardly slidably through the hearings 2&0and 241 above and below a worm wheel 2412 adapted to the screw 231 andthrough bearings 2413 and 2 1-1 above and below a worm wheel 2 15adapted to the screw 205,.there being a slow thread on that portion ofthe screws 205 and 231 which operates the-glib ing device transverselyof the warp strips and a fast thread on that portion of the screws whichengages the worm gears and-245. A roller and pin 246 is carried by theupper end of the yoke 238 and adapted to operate in the groove of thecam 237 so that by rotation .of the cam the worm shaft 239 is operatedvertically thereby rotating the worm wheels 242 and 245'which inturnrotate the screws 205 and 231 thus carrying the gluing devices back andforth acrossthe warp strips.

It is here explained that in the present invention where wood ribbonscomprise the clamp 116.

warp and weft of the fabric the shuttle must clamp upon and support thestrips of weft through their entire length in order that they may beplaced firmly in the weave and straight across the fabric. In order toeffect such a purpose the shuttle must have two separate movements, onein which the shuttle moves in and out of the loom as a shuttle, and thesecond in which the shuttle operates to place the weft strips in placein the weave. This latter movement is exceptional for a shuttle and hasbeen termed the put of the shuttle throughout this specification.

In the operation of the device, the two gangs of reels 10 and 11 beingwound full of wood strips, the wood strips being preferably of spruceand having a thickness more or less fourteen one thousands of an inchcut from lumber having any suitable length, the ends of the strips beingglued together to form a continuous ribbon; the individual. reels arethen mounted in position, carried upon the stub shafts 20.

The ends of each strip which comprises the warp of the fabric to bewoven is then carried through a tension spring 28 or 32, between therollers 29 and 33, through one of the guides 30 or 3 1, between therollers 31 and 35, through the heald frames 51 and 5 2, through the weftclamp 100, through the holding clamp 102 and through the feeder Themachine is then rotated until the feeder clamp closes down upon the endsof the warp strips. A reel 131 carrying a ribbon of the same material asthe warp is mounted on the arm 130 of the shuttle carriage. This ribbonof wood comprises the weft for the fabric and its end is passed throughthe tension spring 133 over the roller 13%, through the guide 135 andalong through the groove 158 of the shuttle. The clamping means of theshuttle is then clamped upon the strip and the device is ready foroperation.

A power belt is passed over a pulley 121 on. the drive shaft 78 and byits rotation the earn 141 is rotated causing a vertical movement of thescrew 1&7 and a rotation of the gear wheel 14-8 thereby effecting areciprocation of the shuttle back and forth between the upper and lowerstrips of the warp which is hold separated by the heald frames. Therotation of the main shaft also rotates the transverse shaft 68 throughthe pinion gear 82 on the main shaft rotating a gear 89 twice its sizeupon the transverse shaft. T he bevel gear 89 on the left hand side ofthe device fixed to the transverse shaft therefore rotates the piniongear 93, which is half its size, upon the shaft 90 thus causing theshaft 90 to rotate with the same speed as the drive shaft 7 8 andoperating the pairs of cams 84c and 9 1, 85 and 95, 87 and 96, and 88and 99 in unison except that they are operating in reverse directions ofrotation. "Thus by the single sheet for some purposes or it may belaminated with other sheets of the same material more or less corrugatedbeing interlaid again with fiat sheets of the material so that athickness of several layers may be built up having a great stiffness.Such a product, it is intended, is to be used for the surfaces orcovering of aeroplane wings and possibly for automobile tops and thelike.

The strips of wood used in the manufacture of the above article arepreferably cut from the spruce lumber by special machinery and forordinary purposes have a width ofl inch and a thickness of aboutfourteen thousandths of an inch, they being glued together end on end toform a continuous ribbon of the material.

It is obvious that the arrangement of the different parts of theinvention relative to one another might be altered and the means foroperating them might be modified and that various other changes might bemade in the invention as set forth without departing from the spiritthereof as claimed.
